红外型空空导弹攻击区“黑洞”研究

The Research about the “Black Hole” Appeared in the Attack Zone of IR Air to air Missile

对某型第三代红外空空导弹的不可攻击区，即“黑洞”进行了分析，并利用数学仿真进行验证，证实了“黑洞”的存在。通过对攻击区中“黑洞”产生的原因和主要影响因素的研究和分析，以及在对比例导引系数进行优化设计的基础上，提出了消除“黑洞”的方法和工程实施途径。仿真计算结果表明，该方法能有效地提高导弹的制导精度，消除了攻击区中的“黑洞”，改善了导弹的全向攻击能力。

In this paper,the reasons of forming the “Black Hole” that is a zone in which the guidance accuracy of missile is very poor and it is difficult to kill target and the factors influenced on “Black Hole” in the third generation IR combat air to air missile attack zone are investigated by analysing the missile guidance rules,and the numerical simulation test has been done. Meanwhile on the base of the proportional guidance coefficient optimum design,this paper gives a specific method and engineering measure for eliminating the “Black Hole”.The simulation results shown that this method can enhance the guidance accuracy of missile and improve the all aspect attack capability of missile.
